The Beauceron is France's largest native herding dog, developed on the plains around Chartres to move and guard big flocks over long distances. That history explains the weatherproof black-and-tan or harlequin coat, the tan "red stockings" on the legs and the double dewclaws on each hind leg. Beaucerons also served as messenger and sentry dogs in both world wars.
Most Beaucerons are intelligent, confident and loyal to their family, and reserved with strangers. Many are sensitive to tone and bond closely with one or two people. They mature slowly, often not settling until about three years old, so adopters need time for daily exercise, ongoing socialization and calm, consistent training. Beaucerons run roughly 70 to 110 pounds, and each dog varies.
